New in 19, when you have a selection and type a ", it puts quotes around the whole selection.
I forget what this is called, and it doesn't appear to have a feature notification.
I seem to run into the case pretty often where it does the wrong thing for me.
For example, given this line of code,
printf("Hello there code\n");
I will select
code\n");then type
", arg1);then result is
printf("Hello there ", arg1);"
instead of what I wanted,
printf("Hello there ", arg1);
It should be a little smarter
